2015-03-25erts: Combine flat and hash maps under one unifying tagBjörn-Egil Dahlberg
2015-03-24erts: Remove HAMT_SUBTAG_NODE_ARRAYSverker Eriksson
This will also fix a bug in term_to_binary treating full nodes as tuples and emiting LIST_EXT for leafs.
2015-03-19erts: Ensure maps uses _rel functions in halfwordBjörn-Egil Dahlberg
2015-03-13erts: Restrict GCC intrinsics by compiler versionBjörn-Egil Dahlberg
Intrinsics __builtin_clz and __builtin_popcount are only valid on GCC version 3.4 and above.
2015-03-12erts: Set Maps small limit to 32 itemsBjörn-Egil Dahlberg
Use small limit 3 in debug case
2015-03-12erts: Make hashmap iterator more flexibleSverker Eriksson
to allow mixing of 'next' and 'prev' operations.
2015-03-12erts: Refactor maps naming conventionSverker Eriksson
flatmap: Small map hashmap: Large map map: flatmap or hashmap
2015-03-12erts: Add hashmap_iterator_prev to mapsBjörn-Egil Dahlberg
2015-03-12erts: Tweak over estimation of hashmap size for binary_to_termSverker Eriksson
Strategy: Calculate an over estimation of heap size that will give such a low probability for overflow, that "it will not happen". Scary assumption 1: Uniformly distributed hash values. Scary assumption 2: Tree size is normally distributed (right?)
2015-03-12erts: Reject duplicate keys for hamt in binary_to_termSverker Eriksson
2015-03-12First stab at binary_to_term for hamtSverker Eriksson
with over estimation of heap size.
2015-03-12erts: Refactor hashmap_from_ks_and_vsBjörn-Egil Dahlberg
Use extra key and value if needed.
2015-03-12erts: Fix update_map_assoc instructionBjörn-Egil Dahlberg
Did not build a hashmap once the small limit was exceeded.
2015-03-12erts: Add make_internal_hashSverker Eriksson
2015-03-12erts: Split hashmap_insert to down and upBjörn-Egil Dahlberg
2015-03-12erts: Handle hashmap in get_map_element(s) instructionsBjörn-Egil Dahlberg
2015-03-12erts: Remove erl_hashmap.[ch] filesBjörn-Egil Dahlberg
2015-03-12erts: Move hashmap:from_list/1 to mapsBjörn-Egil Dahlberg
2015-03-12erts: Move hashmap:get/2, find/2 and is_key/2 to mapsBjörn-Egil Dahlberg
2015-03-12erts: Move hashmap:to_list/1, keys/1 and values/1 to mapsBjörn-Egil Dahlberg
2014-08-20Return pointer to value in erts_maps_get()Anthony Ramine
While at it, implement erts_maps_get_rel() for halfword support.
2014-01-29erts: Add map construction to driver APISverker Eriksson
erl_drv_output_term() and erl_drv_send_term() can send messages containing maps with the use of the new ERL_DRV_MAP. The driver API minor version is updated as new functionality is added.
2014-01-29erts: Add NIFs for MapsBjörn-Egil Dahlberg

2014-01-28erts: Introduce more Maps BIFsBjörn-Egil Dahlberg
* map:remove/2 * map:keys/1 * map:values/1 * map:is_key/2 * map:update/3 - Equivalent to ':=' operator in #{ K := V } maps. * map:from_list/1 - map:from_list/1 takes any unsorted key/value list, [{K,V}], and produces a map. Duplicate keys are removed. The latest key is kept. * map:find/2 - Searches for a pair that *equals* input key. * map:merge/2 - Merge two maps to one map.
2014-01-28erts: Initial Map instructions, type and structureBjörn-Egil Dahlberg
